--- Comment #18 from Simon Farnsworth simon.farnsworth@onelan.co.uk 2012-03-15 04:20:56 PDT --- I've spoken with Tvrtko - we think the patch is not quite right.

Specifically, it assumes that we will get appropriate HPD sense when a VGA monitor is connected, but we've come up with two cases where that's not true:

1) DVI-A to VGA adapter plugged in first, monitor plugged in a few minute later. 2) Cheap DVI-A to VGA adapter that doesn't wire up the HPD pin.

Tvrtko's planning to look into this in a bit more depth.
